Error in Try and Except block

Hello, can someone help me ?

using_a_function.py
"""
This is importing a function named `tweet` from a file
    that we unfortunately don't have access to change.

You use it like so:
>>> tweet("Hello this is my tweet")

If the function cannot connect to Twitter,
    the function will raise a `CommunicationError`
If the message is too long,
    the function will raise a `MessageTooLongError`
"""
from twitter import (
    tweet,
    CommunicationError,
    MessageTooLongError)


message = input("What would you like to tweet?  ")
trial_1 = tweet(message)
try:
    print(trial_1) 
except CommunicationError:  
    print("An error occurred attempting to connect to Twitter. Please try again!")

Hi! You're currently 'trying' the wrong thing. You should be trying to write a tweet, but instead, you're trying to print the result of calling the tweet() function.

# this variable is holding the result of calling the tweet function
# and passing in the message
trial_1 = tweet(message)
try:
    # here you are trying to print this result
    print(trial_1) 

Instead:

try:
    # now you're trying to tweet the message
    tweet(message)

I hope this helps!
